`/qllorney Patented .May 23, 1933 WILLIAM G. BUBHANS, l' KINGSTON, NEW YORK LUBBICATING OIL CLABIFIEE Application med November 20, 1931.

This invention relates to an improved lubricating oil clarifying device designed for installation in the oil circulating system of motors, particularly of the internal combustion en e type employed in present da automo iles.

he invention has reference to a novel oil filter which is an improvement on the type of filter illustrated in a patent granted to 1o me under date of June 14, 192.7, and identified as 1,632,461. v. Y

' The present invention is characterized by a number of structural refinements and revisions providing a structure wherein a bodll ily removable and insertible filterin cartridge is the principal feature of dlstinction.

The specific structural details, relative arrangement and association, and commercial features and advantages will become more readily apparent from the following description and drawings.

Inthe drawings:

Fi re 1 is a side elevational view showing t e complete oil clarifier as constructed in accordance with the present invention.

Figure 2 is a top plan view of Figure 1.

Figure?) is a central vertical sectional view with parts in elevation.

Fi re 4 is a lon 'tudinal vertical sectiona view through t e improved bodily removable cartridge.

' Figure 5 is a bottom plan view of said cartridge.

Figure 6 is a fragmentary elevational view of a clamping cross-head'.

Figure 7 is a plan view of a supporting rilg disposed on the interior of the casing.

gure 8 is a fragmentary plan view of a.

follower cup..

Figure 9 is a horizontal section on the line 9-9 of Figure 3.

In the drawings, -it will be seen that the container or casing 'is generally designated by the numeral 1 0 and comprises a shell havl serm No. 576,408.

ing a c lindrical open top body ortion 11 reduce in diameter as Indicate at 12 t0 form an annular shoulder. The bottom ortion of the casing is of semi-'bulbous con guration as indicated at 13 to form a sediment 50 and water collecting trap and this is provided ,with an internally screw-threaded nipple 14 into which the drain cock 15is` tapped.

The numerals 16 designate a suitable at- 55 taching bracket forsecuring the device to a relatively stationary support 17 as shown -in Figure2.'

lAs seenin Figure 3, the oil inlet is d enoted by .the numeral 18 and this is pro- 60 vided with a cut-olf valve 19 of ap ropriate construction. The oil outlet at t e top is distinguished by the numeral 20. The numerals 21 and 22 designate suitable couplings for the circulating pipe sections 23, 24, and 25, it bein understood that the oil enters the clari er through the connection 18, passes upwardly and leaves through the connection 20 where .it is returned by the piping to the crank case.

The internal filtering cartridge is distinguished as a unit by the numeral 26, and this is of composite construction. As seen in Figure 4, it comprises a fabric or gauze bag 27 having a` burlap bottom 28. The bag 75 is open at its top and the mouth portion thereof embraces a felt closing disc 29. This novel container is filled with an appropriate filter 30 which is preferably a mixture of cotton and wool waste material.

The complete cartridge is removably inserted in the. cylindrical body portion 11 and seated on a supporting ring 31 which is in turn seated on the shoulder or ledge 12.

A novel fluid-ti ht closure is provided for the upper end of t e receptacle and this comprises an imperforate cupped cap 31 having a suitable rim 32 provided with a packing ring 33 clamped down on the upper end of the cylindrical body 11. This cap is pro- 34 forming a seat for the adjacent end 'of f the 'clamping screw 35. This clamping of diametrically` screw passes loosely through a hole in the crown portion of a yoke 36 rigidly secured to the cap, and the upper end of the screw is fashioned with a finger-grip 37. i

Attached to the indentat1on 34 is a semispherical apertured follower cup 38 which conforms to and fits snugly down against the rounded end portion'o the cartridge 26, as seen for example in Figure 3. This serves to com ress the filler of the cartridge to insure ey ective results.

I now call attention to a cross bar or cross head 39 having its end portion 40 shaped to co-operate with hooks 41 on the upper ends opposite arms 42 secured to the casing. he central portion 43 of the bar 39 is threaded and the clamping screw is threaded therethrough and rests in the seat 34. Thus by turnmg the screw down the bar 39 backs up in the yVkee er hooks 41 and presses the cover firmly ownagainst the casing. This also forces the follower plate or cup 38'tightly down against the cartridge ,26.

For installation in general, simply connect the ressure` line with a side inlet 18 of the lclari er andy return from top connection 20 to the crank case.v Under no circumstances, on any system, should the return from the clarifier be connected to pressure line or to bearings. It has been found also that in order to realize the utmost value of this clarifier andl when installation ist made on dirty oiled motors, the cartridge should be changed frequently, perhaps every two or three hundred miles until the system is thoroughl cleaned and the oil is clear.

Therea ter, the cartridge may be ,renewed when oil becomes unnecessarily dark or cloudy. y The method of attachment and in-A stallation varies according to the particular type ofoil circulating system in which the clarifier is embodied as 1s obvious. .Y

It is evident that the sediment and water will collect in the trap 13 from which it may be periodically drained by way of the drain cock 15. It is further evident that the oil enters the clarifier at the lower side inlet and circulates around the sediment cap the oil being forced up through the special cartridge and returned to the crank case from thel side top outlet 20.

The following points are a few of the commercial advantages is observed from actual usa e and tests.

1. Save romifty to seventy-five per cent on oil consumption.

2. Eliminates valve vand carbon jobs by at least seventy-live per cent.

3. Eliminates sticky valves.

4. Eliminates water dilution of oil in c-rankcase. v

It is to be understood that changes may be made in the construction and 1n the oombination and arrangement of the several parts provided that such changes fall within the scope of the appended claims.

` I claim:

1. Asy a new article of manufacture, a cartridge for use in an oil clarifier of the class described comprisin a foraminous sack including a cup-like bur ap base portion, a cloth body portion open at its top, a filler of waste, and a disc-like insert of felt over'- lying the upper end portion of the waste and constitutin a closure for the mouth portion of the sac 2. As a new article of manufacture, a cartrid e for use in association with an oil clarifier of the class described comprising a sack` of closely woven fabric having a bottom portion of coarse woven abrio, and a filler in said sack composed of cotton waste.

3. An oil clariienof the class described comprising a casing of cylindrical form open at its top and havin a substantially semi- ,Y

spherica ower end t e upper part of which is of less diameter than the ma or ortion of the cylinder whereby a shoul er 1s formed at the juncture of said lower part with the major part, a ring-shaped plate seated on the shoulder having a small centrally arranged opening, a cartridge located in the casing and seated on the ring-shaped plate, with the central part of its lower end covering the opening in the ring-shaped plate, said cartridge havm a rounded upper end, a cap for closin' t e upper end of the casing and having a domeshaped part formed with a central depression, a perforated dome shaped follower late having its central part connected to the ower face of the depression part of the cap and enga ing the upper end of the cartrid e, a yoke iaving its extremities connecte with exterior parts of the cap, a cross bar passing between the yoke. and the cap and having a threaded hol therein, a screw assing loosely through the bight of the yo e `and thru the threaded hole in the cross bar with its lower end entering the depressionl in the cap, upstanding members connected to opposite sides of the top part of the casing and having hookshaped upper ends for receiving the ends of the cross bar, inlet Ameans connected with the Iower art of the clinder below lthe ring-shapefplate and out et meansconnocted with the top part of the cylinder.

4. As a. new article of manufacture, a. filteringl cartridge comprising a sack formed of foraminous material, a bottom formin portion for the sack composed of materi of coarser mesh than that of the sack, the top of the sack being open, a filler of filtering material in said lsack and a closure for the top of the sack formed of fabric.
